TL;DR: PCI DSS v4.0.1 expands internal penetration testing scope beyond traditional network segments to include cloud infrastructure, SaaS applications, and build pipelines such as GitHub Actions, Azure DevOps, and Jenkins, because credential theft and pipeline compromise can provide direct paths into the CDE, according to Bishop Fox. For IAM and PAM teams, segmentation must now be validated across authentication, authorization, and identity-bearing systems, not just network boundaries.
Editorial analysis by NHI Mgmt Group, based on content published by Bishop Fox: “Enabling Proper PCI Testing with Internal Penetration Tests”.
Key questions
Q: What breaks when PCI segmentation does not cover cloud and CI/CD access paths?
A: Segmentation can appear sound at the network layer while identity-bearing paths still reach the CDE through cloud tenants, SaaS apps, or deployment systems.
Q: Why do authenticated SaaS and pipeline paths increase PCI CDE risk?
A: Because they can function as trusted bridges into systems that store, process, or deploy into the CDE.
Q: What are the signs that PCI internal testing scope is too narrow?
A: Common indicators are a scope that covers only subnets and firewalls, no inventory of cloud components, no review of SaaS access, and no inclusion of build tools that can deploy into CDE-connected systems.
Practitioner guidance
- Map all CDE-relevant identity paths Document every cloud account, SaaS tenant, service principal, and human account that can reach data, applications, or deployment systems tied to the CDE.
- Add CI/CD systems to segmentation scope Treat GitHub Actions, Azure DevOps, Jenkins, and other build tools as in-scope components when they can deploy to or modify CDE-connected systems.
- Test authentication as a segmentation control Validate whether stolen credentials, federated sessions, or shared SaaS access can bypass network isolation and expose cardholder data.
Bottom line: PCI DSS v4.0.1 expands internal testing into cloud, SaaS, and CI/CD systems that can influence the CDE, which makes identity paths part of the scope boundary.

PCI scoping has become an identity governance exercise, not just a network test. Once cloud tenants, SaaS applications, and build pipelines are in scope, the decisive question is who or what can reach the CDE through authenticated paths. That changes the control problem from segment maps to entitlement maps. Practitioners should treat PCI scoping as a review of access relationships, not only infrastructure boundaries.
A few things that frame the scale:
- 59% of compromised machines in a major 2025 supply chain attack were CI/CD runners rather than personal workstations, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: Who is accountable for deciding whether cloud, SaaS, and pipelines are in PCI scope?
A: The entity must document and confirm scope, but the QSA ultimately judges whether the segmentation evidence is sufficient. Practitioners therefore need a clear ownership chain across security, IAM, cloud, and DevOps so that access paths into the CDE are not left outside the test plan.
